Ingredients

• 2 1/2 pounds new or baby Yukon Gold potatoes, scrubbed
• 4 large eggs, room temperature
• 1 teaspoon mustard seeds
• 3 tablespoons apple cider vinegar
• 2 tablespoons whole grain mustard
• 1 teaspoon honey
• 1/3 cup olive oil
• Kosher salt, freshly ground pepper
• 1 cup parsley leaves with tender stems
• 3 tablespoons coarsely chopped dill pickles
• 2 tablespoons chopped fresh chives

Instructions

1. Steam potatoes, covered, in a metal steamer basket set in a large pot over boiling water until tender, 20–30 minutes, depending on size. Transfer to a plate and let cool.
2. Meanwhile, cook eggs in a large saucepan of boiling water until whites are set and yolks are still slightly soft, 7 minutes. Drain; transfer eggs to a bowl of ice water and chill until cold. Drain and peel; set eggs aside.
3. Toast mustard seeds in a dry small skillet over medium-low heat, tossing constantly, until seeds start to pop, about 1 minute. Transfer to a small bowl (be ready with bowl; once seeds get going, it's chaos).
4. Whisk vinegar, mustard, and honey in a large bowl. Whisking constantly, gradually add oil; whisk until emulsified. Season with salt and pepper. Set 3 tablespoons vinaigrette aside for drizzling.
5. Halve potatoes and add to bowl with vinaigrette. Add parsley and toss to coat; season with salt and pepper. Transfer to a platter. Halve reserved eggs and tuck in between potatoes. Drizzle with reserved vinaigrette. Top with pickles, chives, and toasted mustard seeds.
6. Eggs can be boiled 1 day ahead; drain, cover, and chill. Peel just before using. Vinaigrette can be made 3 days ahead; cover and chill.
